JOSEPH M. MOORE, 0F UN'ADILLA, NEW YORK.

SILO-DOOR.

T all whom) it may concern Be'it known that I, J OSEPH M. MOORE, a citizen of theUnited States, residing at Unadilla, in the county of Otsego and State of New York, have invented a new and useful Silo-Door, of which the following is a specification.

This invention relates to silos, one of its objects being to'provide novel means for connecting together at the door of the silo the ends of the hoops so that the expensive lugs heretofore used may be dispensed with and the ends of the hoops will not be caused to project into the door opening when tightened. v

Another object is to provide a connecting bar between the ends of each hoop which bar extends across the door opening and'is adjustable relative to the stiles of the door so as thus to adjust the distance between the door stiles.

A further object is to provide a door having a latch of novel form whereby the door can be readily locked or unlocked while inposition in the door opening.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :Figure 1 is a front elevation of a silo having the present improvements combined therewith. Fig. 2 is a perspective view of one of the cross bars used in connection with a silo hoop. Fig. 3 is an enlarged perspective view of one of the latch members of'a. silo door. Fig. 4c is a transverse section through the silo door on line DE Fig. 1. Fig. 5 is a section on line FG Fig. 1.

Referring to the figures by characters of reference A designates a silo structure having the usual door stiles 'B. Extending around the silo are hoops 1 which are ordinarilv connected to lugs secured to the stiles B. In the present instance, however. across.

I Specification of Letters Patent.

provided, at each end, with an enlargement drawn tightly aboutthe silo by a person standing on one of the lower bars 2. Thus it is unnecessary to use a ladder and to climb about the silo, as heretofore, when it has been desired to tighten the hoops.

.Oneof the enlarged portions 3 of the bar 2 has spaced openings '3 while the other enlarged portion 3 is provided with upper and lower longitudinal slots 6 interposed between outstanding lugs or shoulders 7. A circulardisk 8 is interposed between'the lugs 7 and has an eccentric boss 8 on its inner face and which extends into one of the slots 6 while an angular head or nut 8 is formed on the outer face of the disk. A. bolt 9 is extended through the stiles B, boss 8, disk 8 and head 8 and can be tightened by nuts, in the usual manner, so as thus to bind the disk or eccentric 8 upon the enlarged portion 3 and between the shoulders 7. Another bolt 9 may be extended into the other slot v6 from the stile B and additional fastening bolts 9 can also be extended through the openings 3 from the other stile B.

hen it is desired to draw the stiles B toward each other, the bolts 9 and 9 extending into the slots 6 are loosened. A wrench is then placed on thehead 8 of the eccening the nuts onto the hoop, said hoop can be trio and said eccentric is rotated to the right so as to press agalnst the outer lug or shoul- I der 7, thus causing the bar 2 to pull upon spread apart the stiles B, the operation above described is reversed.

For the purpose of closing the door open- 1 I ing, a series of doors 0 is utilized, these doors being adapted to project, at their edges, into rabbets 1) formed in the inner 1 sides of the stiles B. A bail 10 extends transversely of and is connected to each door C, each side of each bail being provided with.

a pair of cam-shaped projections 11 and 12 designed to cooperate with a. cam-shaped projection 13 outstanding from a pivoted latch 14 mounted on one side portion of the door. This latch is so located that, when the door is seated in the rabbets b, it is possible to swing the latches so that they will lap the outer faces of the stiles B. The camsl1aped projections 11, 12 and 13 are so shaped and proportioned that, when the bail on the door to which the latches are connected is swung downwardly, the projections 11 will ride upon the projections 13 and thus draw them upwardly, thereby causing the outerends of the latches to swing downwardly and outwardly so as to lap the outer faces of the stiles B, as shown upon the upper part of Fig. 1. This swinging of the latches it causes the curved cam projections 13 to swing upwardly so as to lap the projections 12. Consequently, when the bail 10 is swung upwardly, the projections 12 will push against the inner or concaved edges of the projections 18, thus swinging said projections downwardly and causing the latches 14: to move upwardly and in:

wardly out of engagement with the stiles B. Thus the door will be released.

l/Vhat is claimed is The combination with a silo structure including door stiles, of a bar extending across the door opening and fixedly secured to one stile, there being outstanding projections upon the bar and slots within the bar and between the projections, an eccentric mounted for rotation between the projections, a boss projecting therefrom and into one of the slots, means extending through the boss and into the stile for binding the eccentric upon the bar, said eccentric having means for engagement with an adjusting tool, and a hoop secured at its ends to the bar.

In testimony that I claim the foregoing as my own, I have hereto affixed my sig nature in the presence of two witnesses.
